The Tokina RMC 35-70mm f/3.5-4.8 was a compact manual focus standard zoom from Tokina's RMC range, sold through the late 1970s and 1980s as an affordable alternative to a fixed 50mm lens for 35mm SLR owners wanting modest wide-angle reach.
It uses a two-touch zoom-and-focus design typical of RMC-badged lenses, with a manual click-stop aperture ring and Tokina's period multi-coating. Maximum aperture varies from f/3.5 at 35mm to f/4.8 at 70mm, keeping the lens small and light for everyday carry.
Performance is solid in the middle of the zoom range and softens somewhat at 35mm wide open, in line with other budget standard zooms of its generation. It is not a specialist lens but covers everyday focal lengths competently once stopped down a little.
Widely available secondhand in M42, Pentax K, Canon FD, Nikon F, Minolta MD, Olympus OM and Konica AR mounts, and usually inexpensive. Buyers should check the zoom action for grease creep and confirm the aperture ring clicks land cleanly at each stop.
